FDA Approves Komzifti (ziftomenib) for the Treatment of Adults with Relapsed or Refractory NPM1-Mutated Acute Myeloid Leukemia

Kura Oncology, Inc. (Nasdaq: KURA) and Kyowa Kirin Co., Ltd. (TSE: 4151)  announced the U.S. Food and Drug Administration (FDA)   approval of Komzifti™ (ziftomenib) for adult patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) with a susceptible NPM1 mutation who have no satisfactory alternative treatment options. Komzifti is the first and only once-daily, oral menin inhibitor approved for R/R NPM1-mutated (NPM1-m) AML, a devastating blood cancer with limited treatment options.

“Komzifti combines compelling efficacy, a favorable safety profile, compatibility with concomitant medications, and convenient once-daily oral administration in a population with few effective treatment options. These features highlight Komzifti’s potential to serve as the menin inhibitor of choice in its approved indication,” said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. “Together with our partner, Kyowa Kirin, we remain committed to advancing development of Komzifti across the treatment continuum for AML, where its best-in-class profile offers potential for even greater impact in combination regimens and earlier lines of therapy. We are fully prepared to launch Komzifti today and deliver this new medicine to patients in need.”

NPM1 mutations are among the most common founder mutations in AML, occurring in approximately 30% of cases. Historically, approximately 20% of patients with NPM1-m AML do not respond to front-line therapy. Of those who do respond, 70% will relapse within 3 years, most within 12 months. Early relapse and declining survival with each recurrence underscore the urgent need for treatment approaches that deliver lasting remission.

Approval is supported by the pivotal KOMET-001 trial (NCT04067336), which evaluated Komzifti’s safety and efficacy in 112 R/R NPM1-m AML patients. The rate of complete remission (CR) plus CR with partial hematologic recovery (CRh) was 21.4% (95% CI: 14.2, 30.2). The median duration of CR+CRh was 5.0 months (95% CI: 1.9, 8.1) and the median time to first response in patients who achieved a CR or CRh was 2.7 months (range: 0.9 to 15 months). 88% of patients who achieved CR or CRh did so within 6 months of initiating Komzifti. These data from the Prescribing Information are generally consistent with findings recently published in the Journal of Clinical Oncology.1

“Komzifti addresses a critical need for adult patients with R/R NPM1-m AML, many of whom are older and unable to tolerate intensive chemotherapy or transplant,” said Eunice Wang, M.D., Chief of the Leukemia Service and Professor of Oncology at Roswell Park Comprehensive Cancer Center. “The clinical data demonstrate deep and durable responses with a manageable safety profile, including no drug-drug interactions and no Boxed Warnings for QTc prolongation or Torsades de Pointes – key advantages for patients on multiple concurrent medications. This approval equips physicians with a new oral therapy to integrate into care and improve outcomes for this vulnerable patient population.”

The most common adverse reactions (≥20%), including laboratory abnormalities, were aspartate aminotransferase increased, infection without an identified pathogen, potassium decreased, albumin decreased, alanine aminotransferase increased, sodium decreased, creatinine increased, alkaline phosphatase increased, hemorrhage, diarrhea, nausea, fatigue, edema, bacterial infection, musculoskeletal pain, bilirubin increased, potassium increased, differentiation syndrome, pruritus, febrile neutropenia, and transaminases increased. Komzifti includes a Boxed Warning for differentiation syndrome, a well-studied mechanism-based risk in drugs that restore differentiation. Absence of clinically meaningful drug-drug interactions can ease the use of Komzifti with concomitant therapies, including those that cause QTc interval prolongation. QTc interval prolongation was ≤ Grade 3 in 12% of patients and no Grade 4 or Grade 5 QTc interval prolongation was reported. QTc interval prolongation of any cause occurred in 10% of the 70 patients 65 years of age or older.

“The approval of Komzifti underscores our commitment to advancing precision medicines to address the genetic drivers of disease in hematology and oncology,” said Takeyoshi Yamashita, Ph.D., Executive Vice President and Chief Medical Officer of Kyowa Kirin. “In AML, where many patients face severe disease progression and limited treatment options, the evolution toward targeted therapies such as Komzifti represents a major step forward and offers potential to transform existing standards of care. We are proud to partner with Kura Oncology in bringing this important therapy to patients and their families.”

In November 2024, Kura Oncology and Kyowa Kirin entered into a global strategic collaboration to develop and commercialize Komzifti. The collaboration builds on Kyowa Kirin’s leadership and expertise in hematologic malignancies. Under the terms of the collaboration, Kura leads development, regulatory and commercial strategy in the U.S. and is responsible for manufacturing Komzifti. The companies will jointly perform certain commercialization activities in accordance with a co-created U.S. territory commercialization plan. Outside the U.S., Kyowa Kirin leads development, regulatory and commercial strategy and is responsible for commercializing Komzifti.

As part of its commitment to helping patients access Komzifti, Kura has established a support program, Kura RxKonnect™, to minimize barriers to access and reimbursement for appropriate patients prescribed Komzifti. Kura RxKonnect is available 8:00 am – 8:00 pm ET by phone at (844) KuraPSP (844-587-2777) or online at www.KuraRxKonnect.com.

FDA Grants Accelerated Approval to Hyrnuo (sevabertinib) for Non-Squamous Non-Small Cell Lung Cancer

Following Priority Review and Breakthrough Therapy Designation, the U.S. Food and Drug Administration (FDA) has granted accelerated approval for Hyrnuo (sevabertinib), for the treatment of adult patients with locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC) whose tumors have human epidermal growth factor receptor 2 (HER2) tyrosine kinase domain activating mutations, as detected by an FDA-approved test, and who have received a prior systemic therapy. Sevabertinib is an oral, reversible, small molecule, tyrosine kinase inhibitor (TKI).

“The FDA’s approval of sevabertinib elevates the standard of care and provides a new treatment option for patients living with HER2-mutant NSCLC, which is a challenging disease with limited therapies available,” said SOHO-01 lead trialist, Xiuning Le, MD, PhD, The University of Texas MD Anderson Cancer Center, Houston, Texas. “Clinical results from the SOHO-01 trial showed that sevabertinib is effective with a manageable safety profile.”

The FDA approved this indication for sevabertinib under accelerated approval based on objective response rate (ORR) and duration of response (DOR) data from the ongoing Phase I/II SOHO-01 trial (NCT05099172) in patients with advanced NSCLC harboring a HER2-activating mutation, with disease progression after ≥1 systemic therapies for advanced disease. Continued approval of sevabertinib for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

Results from the Phase I/II SOHO-01 trial demonstrated for patients naïve to HER2 targeted therapy an ORR of 71% (95% CI: 59%-82%, N=70); 2.9% of patients had a complete response and 69% of patients had a partial response. Median DOR was 9.2 months (95% CI, 6.3–15.0, N=50). Sevabertinib demonstrated a manageable safety profile with a 3.7% discontinuation rate. In the pooled safety population, the most common (> 20%) adverse reactions were diarrhea (87%), rash (66%), paronychia (33%), stomatitis (29%) and nausea (21%).

Positive results from the Phase I/II SOHO-01 trial were presented at the European Society for Medical Oncology (ESMO) Congress 2025 and simultaneously published in the New England Journal of Medicine.0F[1]

“Globally, it is estimated that up to 84,000 people are diagnosed with NSCLC harboring a HER2 mutation each year,” said Christian Rommel, Ph.D., Head of Research and Development at Bayer’s Pharmaceuticals Division. “At Bayer our oncology R&D strategy is centered on precision drug development which is designed to help us address critical unmet medical needs through the advancement of innovative therapies. Today's FDA approval of sevabertinib exemplifies this approach, delivering a targeted treatment specifically for patients with advanced HER2-mutant NSCLC. This significant milestone underscores our unwavering commitment to transforming cancer care by delivering meaningful therapies that have the potential to improve outcomes and extend survival for people living with cancer.”

In 2024, both the U.S. FDA and the CDE in China granted sevabertinib Breakthrough Therapy designation indicating that the compound has the potential to provide substantial improvement over existing therapies in NSCLC with HER2-activating mutations. China accepted a new drug application (NDA) for sevabertinib in July 2025.

FDA Approves Cardamyst (etripamil) Nasal Spray for Adults with Paroxysmal Supraventricular Tachycardia

Milestone Pharmaceuticals Inc. (Nasdaq: MIST) announced  the U.S. Food and Drug Administration (FDA) approved its first commercial product, Cardamyst (etripamil) nasal spray, a prescription medication for the conversion of acute symptomatic episodes of paroxysmal supraventricular tachycardia (PSVT) to sinus rhythm in adults. This approval marks the first time that more than two million Americans with PSVT will have a rapid-acting treatment option they can self-administer outside the emergency department or other healthcare setting. Cardamyst is expected to be available in retail pharmacies in the first quarter of 2026.

Cardamyst nasal spray is a novel and rapid-acting calcium channel blocker delivered when needed to treat often highly symptomatic and unpredictable episodes of PSVT. With Cardamyst, adults with PSVT can be prepared wherever and whenever episodes occur, providing them with active management and a greater sense of control of their condition.

“Cardamyst is a novel at-the-ready treatment option that addresses the unpredictable impact of PSVT by offering patients the freedom to manage episodes anytime and anywhere,” said Joseph Oliveto, President and Chief Executive Officer of Milestone Pharmaceuticals. “The FDA approval of Cardamyst is a watershed moment for Milestone and a gratifying event for our team members, patients, clinical investigators, and health care providers who participated in the development program, all of whom I sincerely thank for their dedication, counsel, and collaboration toward this important achievement.”

“Some people with PSVT have endured years of anxiety, fearing their next episode and the stress and disruption of emergency department visits,” said James Ip, M.D., FACC, FHRS, an etripamil investigator. “Cardamyst will give many of them the ability to administer a medication themselves that can quickly stop their PSVT episode and potentially avoid a hospital trip or a call to emergency services.”

Cardamyst Clinical Data

The FDA approval of Cardamyst is supported by a robust clinical trial program based on safety data from more than 1,800 participants and more than 2,000 episodes of PSVT. This includes the successful Phase 3 RAPID trial, a global, randomized, double-blind comparison of Cardamyst vs. placebo, published in The Lancet in 2023. In clinical studies, participants using Cardamyst were two times more likely to convert symptomatic PSVT to sinus rhythm and did so more than three times faster compared with placebo. The RAPID trial achieved its primary endpoint with 64% of those who self-administered Cardamyst (N=99) converting from supraventricular tachycardia (SVT) to sinus rhythm within 30 minutes compared to 31% on placebo (N=85) (HR = 2.62; p<0.001). At one hour, the benefit was demonstrated in 73% of participants. In addition, significant reductions in time to conversion in those who took Cardamyst were evident early and durable, with a median time to conversion of 17 minutes (95% CI: 13.4, 26.5) for those treated with Cardamyst vs. 54 minutes (95% CI: 38.7, 87.3) for those treated with placebo.

A consistent safety profile and treatment effects were observed across all subgroups, including participants concurrently on beta blockers or calcium channel blockers. The most frequent adverse events occurring in ≥5% of participants in randomized clinical trials were mild-to-moderate and transient in nature, including local-site nasal discomfort, nasal congestion, rhinorrhea, throat irritation, and epistaxis. Less than 2% of trial participants discontinued therapy due to adverse events.

For more safety information about Cardamyst, please see Important Safety Information below. For the latest information about the product availability, please see https://milestonepharma.com/.

PSVT, also called SVT, is characterized by episodes of abnormally fast heart rate. Most people with PSVT experience multiple sustained episodes that require treatment on an annual basis. Until now, successful treatment options typically required IV administration in healthcare settings, creating stress and costs for patients and their insurers. Cardamyst offers a new approach to treat episodes of PSVT, enabling adults to self-administer the medication at the onset of symptoms. For more information, please visit SVTHearttoHeart.com.

“Our goal is that Cardamyst will become a trusted and essential solution for healthcare providers and their patients,” said Lorenz Muller, Chief Commercial Officer of Milestone. “Our team is focused on making Cardamyst available to adults with PSVT as quickly as possible, including actively working to secure insurance coverage and begin the distribution of the product through retail pharmacies.”

Annette Greene, Cardamyst clinical trial participant and administrator of the Supraventricular Tachycardia Group on Facebook, with more than 30,000 members, said, “Adults with SVT have been waiting a long time for the day when they can confidently self-administer Cardamyst to treat their SVT episodes. It is very exciting that the day has become a reality.”

Regarding future R&D, Milestone is poised to enter a Phase 3 program in atrial fibrillation with rapid ventricular rate (AFib-RVR), particularly on the strength of the successful ReVeRA Phase 2 trial in AFib-RVR, results of which were published in Circulation: Arrhythmia and Electrophysiology. Incorporating FDA’s guidance, Milestone has developed a Phase 3 registrational program to evaluate self-administered etripamil as a potential treatment for patients with AFib-RVR. When completed, the Company will be following a supplemental New Drug Application (sNDA) regulatory approval pathway for a potential second indication for etripamil in AFib-RVR. As such, Milestone will leverage the approved PSVT indication and the PSVT program data, along with a single pivotal Phase 3 study in patients with AFib-RVR.

FDA Approves Nuzolvence (zoliflodacin) for the Treatment of Uncomplicated Urogenital Gonorrhea in Adults and Adolescents

Innoviva Specialty Therapeutics, a subsidiary of Innoviva, Inc. (NASDAQ: INVA),   announced   the U.S. Food and Drug Administration (FDA)  approval of Nuzolvence (zoliflodacin) for oral suspension, a first-in-class, single-dose oral medication for the treatment of uncomplicated urogenital gonorrhea in adults and pediatric patients 12 years and older weighing at least 35 kg. The development of Nuzolvence was part of a private, not-for-profit collaboration with The Global Antibiotic Research and Development Partnership (GARDP), which sponsored and led the Phase 3 clinical trial that supported FDA approval.

“The FDA’s approval of Nuzolvence marks a pivotal moment for patients and the broader healthcare community managing gonorrhea infections. For the first time in decades, both patients and their healthcare providers will have a single-dose, oral treatment option for uncomplicated urogenital gonorrhea,” said David Altarac, M.D., Chief Medical Officer, Innoviva Specialty Therapeutics. “This achievement underscores our commitment to advancing innovative therapies for infectious diseases and fighting antimicrobial resistance. It highlights the strength of our development capabilities, as well as our collaboration with GARDP and the global scientific community.”

Gonorrhea is the second most common sexually transmitted bacterial infection worldwide, with more than 82 million new cases each year. In the United States alone, the Centers for Disease Control and Prevention (CDC) estimates that over 543,000 cases are reported each year and over 1 million incident cases occur annually,3 underscoring the significant public health impact. The highest rates are seen among sexually active men ages 20-24, though anyone who has unprotected sex can be at risk.4 Without timely treatment, gonorrhea can lead to serious and potentially permanent health complications.

"The decades-long absence of new gonorrhea treatments, combined with rising global antibiotic resistance, has created significant challenges in managing this common but potentially serious sexually transmitted infection," said Edward W. Hook III, M.D., Professor Emeritus of Medicine, University of Alabama at Birmingham, and lead investigator of the Phase 3 Nuzolvence trial. “In the pivotal Phase 3 study, Nuzolvence demonstrated non-inferiority compared to the current standard injectable therapy, including in infections caused by drug-resistant strains, while offering the convenience of a single oral dose.”

“A new antibiotic that does not require injection and can be used for patients who are allergic to penicillin or related drugs meets two important unmet needs in the treatment of gonorrhea,” added Dr. Hook.

The emergence and spread of global drug-resistant infections have led the World Health Organization (WHO) to identify antimicrobial resistance as one of the 10 most critical global health threats.5 The bacterium Neisseria gonorrhoeae has developed resistance to most classes of antibiotics used to treat these infections, including cephalosporins such as ceftriaxone, an injectable treatment, which is the currently recommended first line therapy for uncomplicated urogenital gonorrhea.

The Company plans to commercialize Nuzolvence in the second half of 2026, either in collaboration with a commercialization partner or independently.

I’m pleased that the approved label and REMS reflect the distinct characteristics of Myqorzo including a straightforward, flexible dosing regimen, no requirement for drug-drug interaction monitoring and a predictable safety profile. I am profoundly grateful for the many years of passion and persistence shown by patients with obstructive HCM, as well as healthcare professionals, advocates, partners and employees who have contributed so importantly to reaching this key milestone.”

The full U.S. Prescribing Information for Myqorzo includes a Boxed WARNING for the risk of heart failure. Myqorzo reduces left ventricular ejection fraction (LVEF) and can cause heart failure due to systolic dysfunction. Echocardiogram assessments are required prior to and during treatment with Myqorzo to monitor for systolic dysfunction. Initiation of Myqorzo in patients LVEF <55% is not recommended. Decrease the dose of Myqorzo if LVEF <50% and ≥40%. Interrupt the dose of Myqorzo if LVEF <40% or if the patient experiences heart failure symptoms or worsening clinical status due to systolic dysfunction. Because of the risk of heart failure due to systolic dysfunction, Myqorzo is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the Myqorzo REMS Program. Please see additional Important Safety Information including Boxed WARNING below.

Myqorzo is expected to be available in the U.S. in the second half of January 2026. Cytokinetics will support patients with Myqorzo & You™, a personalized program for patients prescribed Myqorzo in the U.S. to help navigate the treatment journey, provide disease and product education, and offer support with insurance benefits investigations or financial assistance for those eligible. For more information, call 833-Myqorzo (833-697-6796).

“HCM is a heart muscle disease associated with a significant symptom burden. This approval of a new drug, Myqorzo, represents a meaningful addition to the treatment options available for symptomatic obstructive HCM patients,” said Martin Maron, M.D., Director, Hypertrophic Cardiomyopathy Center, Lahey Hospital and Medical Center, and Principal Investigator of SEQUOIA-HCM. “In SEQUOIA-HCM, Myqorzo improved exercise capacity and reduced symptoms while also being well-tolerated. For these reasons, Myqorzo represents an important step forward in how we care for people living with obstructive HCM.”

FDA Approves Aqvesme (mitapivat) for the Treatment of Anemia in Adults with Alpha- or Beta-Thalassemia

Agios Pharmaceuticals, Inc. (Nasdaq: AGIO), a commercial-stage biopharmaceutical company focused on delivering innovative medicines for patients with rare diseases,  announced the U.S. Food and Drug Administration (FDA) approval of  Aqvesme (mitapivat), an oral pyruvate kinase (PK) activator, for the treatment of anemia in adults with alpha- or beta-thalassemia. With this approved indication, Aqvesme becomes the only FDA-approved medicine for anemia in both non-transfusion-dependent and transfusion-dependent alpha- or beta-thalassemia.

“Thalassemia is a debilitating disease that demands lifelong management and vigilant monitoring for many life-threatening complications, such as blood clots, heart disease, and liver disease. Despite its severity, treatments have historically been limited, leaving some patients without any options,” said Hanny Al-Samkari, M.D., Peggy S. Blitz Endowed Chair in Hematology/Oncology at Mass General Brigham Cancer Institute, Associate Professor at Harvard Medical School, and an investigator for the mitapivat thalassemia Phase 3 clinical program. “The ENERGIZE and ENERGIZE-T Phase 3 trial results demonstrate that Aqvesme can help address anemia, fatigue, and the need for regular transfusions – key challenges of the disease. Today’s FDA approval represents an important step forward for individuals with thalassemia.”

The FDA approval of Aqvesme in thalassemia is based on results from the global, randomized, double-blind, placebo-controlled ENERGIZE and ENERGIZE-T Phase 3 trials in adults with non-transfusion-dependent and transfusion-dependent alpha- or beta-thalassemia, respectively. A total of 452 patients who are representative of the real-world thalassemia population were enrolled in the trials. The ENERGIZE and ENERGIZE-T Phase 3 trials met all primary and key secondary efficacy endpoints, demonstrating that Aqvesme improves hemolytic anemia and a key quality-of-life measure compared to placebo, including significant reductions in transfusion burden and significant improvements in hemoglobin and fatigue.

“Today is a landmark moment for the thalassemia community, bringing forward an innovative, disease-modifying oral medicine to address the urgent needs of people living with this devastating rare blood disorder,” said Brian Goff, Chief Executive Officer, Agios. “With this approval, Aqvesme becomes the only medicine indicated for the treatment of anemia in both non-transfusion-dependent and transfusion-dependent alpha- or beta-thalassemia. We are deeply grateful to the patients, caregivers, healthcare providers, and advocacy partners who participated in and supported our clinical trials and helped ensure that our efforts reflected their priorities. Our focus now is on ensuring a successful launch and delivering meaningful impact for the community.”

“This year marks 100 years since thalassemia was first described in medical literature, and the progress we’ve made as a community is truly extraordinary,” said Ralph Colasanti, National President, Cooley’s Anemia Foundation. “Innovative medicines like Aqvesme help make this progress possible, offering new hope to patients like me by helping to address the complex needs and challenges of this disease. This approval provides an important new treatment option for the thousands of adults living with thalassemia in the U.S., including those with non-transfusion-dependent thalassemia who previously had no approved alternatives.”

In the ENERGIZE and ENERGIZE-T Phase 3 trials, five patients receiving Aqvesme experienced adverse reactions suggestive of hepatocellular injury (HCI), with two of these patients requiring hospitalization. These adverse reactions occurred within the first six months of exposure, and liver tests improved upon discontinuation of Aqvesme. To mitigate the risk of HCI, Aqvesme is available only through the Aqvesme REMS, a Risk Evaluation and Mitigation Strategy (REMS) program approved by the FDA. The Aqvesme REMS program requires liver tests prior to the first Aqvesme dose, every four weeks thereafter for 24 weeks, and then as clinically indicated. It also includes education and certification requirements for patients, prescribing physicians, and pharmacists, which are common components of REMS programs.

Due to the Aqvesme REMS program, mitapivat will be marketed under the brand name Aqvesme in the U.S. for the thalassemia indication. Mitapivat will continue to be marketed as Pyrukynd® (mitapivat) in the U.S. for the PK deficiency indication, which does not require a REMS program. Outside the U.S., mitapivat will continue to be marketed as Pyrukynd for its PK deficiency and thalassemia indications in regions where it is approved, and will retain this name upon approval in regions currently under regulatory review.

Agios expects Aqvesme to be available in the U.S. in late January 2026, following implementation of the Aqvesme REMS program. For more information, visit Aqvesme.com.

About Thalassemia

Thalassemia is a rare, inherited blood disease that affects the production of hemoglobin, the protein in red blood cells responsible for carrying oxygen throughout the body. The disease is categorized into two main types: alpha-thalassemia and beta-thalassemia, depending on which globin chain of the hemoglobin is affected. By disrupting hemoglobin production, thalassemia reduces the number of circulating red blood cells and shortens their lifespan, which leads to anemia, fatigue, and serious complications.

Some individuals with thalassemia require regular transfusions (classified as transfusion-dependent thalassemia), while others only need them intermittently (classified as non-transfusion-dependent thalassemia). All patients with thalassemia experience a significant disease burden, including comorbidities, reduced quality of life, and shortened life expectancy.

In the U.S., approximately 6,000 adult patients are diagnosed with thalassemia.

About ENERGIZE and ENERGIZE-T

ENERGIZE (NCT04770753) and ENERGIZE-T (NCT04770779) are global, double-blind, placebo-controlled Phase 3 trials evaluating the efficacy and safety of mitapivat in adults with alpha- or beta-thalassemia.

The ENERGIZE trial randomized 194 non-transfusion-dependent alpha- or beta-thalassemia patients 2:1 to receive either mitapivat 100 mg twice daily or placebo. The primary endpoint was hemoglobin response, defined as an increase of ≥1.0 g/dL in average hemoglobin concentration from Week 12 through Week 24 compared with baseline. Key secondary endpoints included changes from baseline in average fatigue scores and in average hemoglobin concentration from Week 12 to Week 24. The trial also assessed safety and tolerability.

The ENERGIZE-T trial randomized 258 transfusion-dependent alpha- or beta-thalassemia patients 2:1 to receive either mitapivat 100 mg twice daily or placebo. The primary endpoint was transfusion reduction response, defined as a ≥50% reduction in transfused red blood cell (RBC) units with a reduction of ≥2 units of RBCs transfused in any consecutive 12-week period through Week 48 compared with baseline. Several transfusion reduction measures were included as key secondary endpoints, and achievement of transfusion independence was a secondary endpoint. The trial also assessed safety and tolerability.

For each trial, patients who completed the double-blind phase had the option to transition into a corresponding open-label extension phase, during which all patients receive mitapivat.

Egetis Announces FDA Acceptance and Priority Review of NDA for Emcitate (tiratricol) for MCT8 Deficiency

Egetis Therapeutics AB (publ) (“Egetis” or the “Company”) (NASDAQ Stockholm: EGTX), today announced that the U.S. Food and Drug Administration (FDA) has accepted the filing of its New Drug Application (NDA) for Emcitate® (tiratricol) for the treatment of MCT8 deficiency. Egetis completed the rolling NDA in January 2026. The application has been granted Priority Review and assigned a Prescription Drug User Fee Act (PDUFA) target action date, or FDA decision date, of September 28, 2026.

NDA submission for Emcitate® successfully validated by the FDA

Priority Review granted and PDUFA target action date set to September 28, 2026

Emcitate® (tiratricol) is eligible to receive a Priority Review Voucher (PRV) upon approval

If approved, Emcitate® (tiratricol) would become the first approved treatment in the United States for MCT8 deficiency

Nicklas Westerholm, CEO of Egetis, commented: “MCT8 deficiency is a rare, devastating, life-shortening disorder with no approved treatment in the U.S. The acceptance of our NDA with Priority Review represents an important step in the path to making Emcitate® (tiratricol) available to MCT8 deficiency patients in the U.S. The Priority Review also highlights the robust dataset we have in this rare genetic disease, with the NDA based on results from Triac Trial I, Triac Trial II, ReTRIACt, EMC Cohort Study, EMC Survival Study and the U.S. Expanded Access Program. We look forward to collaborating with the FDA during the NDA Priority Review process and will in parallel continue to build our medical affairs and market access capabilities towards a potential U.S. launch in the fourth quarter of this year.”

A Priority Review will direct overall attention and resources to the evaluation of applications for drugs that, if approved, would represent significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. A Priority Review means FDA’s goal is to take action on an application within 6 months, compared to 10 months under standard review.

Emcitate® (tiratricol) has previously been granted Rare Pediatric Disease Designation by the FDA and is eligible to receive a Priority Review Voucher (PRV) upon approval, and a PRV was consequently requested in connection with the submission. The transferability of PRVs has created an active secondary market for these vouchers, selling for $150-$205 million per voucher in 2025/26.

FDA Approves Nereus (tradipitant) for the Prevention of Motion Sickness

Vanda Pharmaceuticals Inc. (Vanda) (Nasdaq: VNDA) today announced that the U.S. Food and Drug Administration has approved Nereus (tradipitant), an oral neurokinin-1 (NK-1) receptor antagonist, for the prevention of vomiting induced by motion. This approval marks the first new pharmacologic treatment in motion sickness in over four decades, representing a significant advancement in the understanding and management of this debilitating physiologic response that affects a substantial portion of the population and has long been recognized as a factor affecting military operational readiness.

"This approval underscores the strong scientific evidence in the antiemetic effects of Nereus in motion sickness," said Mihael H. Polymeropoulos, M.D., President, CEO and Chairman of the Board of Vanda Pharmaceuticals. "For the first time in over 40 years, patients have access to a novel therapy grounded in modern neuropharmacology, offering effective prevention without the limitations of existing options. We are proud of this historic milestone and grateful to the Vanda researchers, patients, investigators, and regulators who contributed to this achievement."

The efficacy of Nereus is supported by robust data from three pivotal clinical trials—two Phase 3 real-world provocation studies conducted on boats (Motion Syros and Motion Serifos) and one additional supporting study—with participants who had documented histories of motion sickness. In Motion Syros (n=365), vomiting incidence was 18.3–19.5% with Nereus versus 44.3% with placebo (p<0.0001).1 In Motion Serifos (n=316), vomiting rates were 10.4–18.3% with Nereus versus 37.7% with placebo (p≤0.0014), representing risk reductions of over 50–70%.2 Across the pivotal program, Nereus consistently demonstrated significant reductions in vomiting and a favorable safety profile consistent with acute use.

Motion sickness has been recognized as a critical factor in military operations since World War II, most notably during the D-Day invasion of Normandy in 1944, where severe seasickness impaired the effectiveness of troops, including paratroopers of the 101st Airborne Division deployed in rough Channel crossings and airborne drops. The condition was elevated to a strategic imperative, prompting early research into antiemetic therapies to ensure operational readiness during large-scale troop deployments by sea, air, and land.

Today, motion sickness remains prevalent in civilian life, with approximately 25–30% of adults3 —roughly 65–78 million people in the U.S.—experiencing symptoms during common travel modes such as cars, planes, or boats. Globally, up to one-third of individuals are highly susceptible.4 While most cases are mild, an estimated 5–15% of the population experiences severe, recurrent symptoms that can significantly impact quality of life. This severe segment comprises two key groups: those whose illness is inadequately controlled by existing therapeutic options, leaving them with persistent debilitating symptoms despite treatment, and those whose illness is so severe that it leads to avoidance of engaging in motionprovoking activities altogether, resulting in altered travel plans, missed opportunities, or complete abstention from certain modes of transportation or experiences. Tens of millions seek pharmacologic treatment annually, primarily through over-the-counter options, though many patients opt for prescription therapies when escalating care. Motion sickness arises from a sensory conflict between visual, vestibular, and proprioceptive inputs, triggering the release of substance P and activation of NK-1 receptors in the central nervous system, leading to nausea and vomiting. Nereus's mechanism of action—potent and selective antagonism of NK-1 receptors—directly addresses this pathway.

The approval of Nereus for the prevention of vomiting induced by motion validates its pharmacological profile and paves the way for further exploration of NK-1 antagonism in related vomit-inducing conditions. Vanda is advancing tradipitant in clinical development for gastroparesis, a chronic disorder characterized by delayed gastric emptying and persistent nausea/vomiting, as well as for the prevention of nausea and vomiting induced by GLP-1 receptor agonists—a common side effect impacting adherence in the rapidly growing obesity and diabetes treatment landscape.

Vanda anticipates launching Nereus for the prevention of vomiting induced by motion in the coming months and remains committed to expanding its therapeutic potential across indications driven by substance P-mediated pathways.

FDA Approves Zycubo (copper histidinate) for Children With Menkes Disease

Sentynl Therapeutics Inc. (“Sentynl”), a U.S.-based biopharmaceutical company wholly-owned by Zydus Lifesciences Limited (“Zydus Group”), announced that the U.S. Food and Drug Administration (“FDA”) has approved Zycubo® (copper histidinate) for the treatment of Menkes disease in pediatric patients. This is the first and only treatment approved for Menkes disease, a rare and fatal genetic condition, in the United States. Zycubo® is not indicated for the treatment of Occipital Horn Syndrome.

“Approval is a pivotal step towards achieving our goal of making a meaningful impact on patients, caregivers, and the rare disease community,” said Dr. Sharvil P. Patel, Managing Director, Zydus Lifesciences Limited. “This milestone marks a transformative moment for the Zydus Group and for families affected by Menkes disease. For the first time, patients have access to an approved therapy, offering hope where no options existed. We are proud to advance patient care and deliver innovative solutions to those who need them most.”

Menkes disease is a rare X-linked recessive pediatric disease caused by mutations of the copper transporter ATP7A encoded by the ATP7A gene. Patients with Menkes disease are born with the inability to absorb dietary copper and subsequently have impaired copper transport across the blood-brain barrier, and, until now, there has been no approved treatment in the United States. Zycubo® is a subcutaneous injectable formulation of copper histidinate that restores copper homeostasis and maintains copper levels in patients with Menkes disease.

“Menkes disease presents significant challenges for patients and their families. With no known cure, most untreated patients do not survive beyond three years of age,” said Matt Heck, CEO, Sentynl. “FDA’s approval serves as compelling affirmation that a safe and effective therapy is now available for patients living with this devastating disease.”

The approval is supported by positive topline clinical efficacy results for Zycubo, demonstrating statistically significant improvement in overall survival for Menkes disease subjects who received early treatment (“ET”) with Zycubo, compared to an untreated contemporaneous external control cohort, with a nearly 80% reduction in the risk of death. Median overall survival (“OS”) was 177.1 months for Zycubo ET cohort compared to 17.6 months for the untreated contemporaneous external control cohort.

The most common adverse reactions (incidence ≥7%) were pneumonia, viral infection, respiratory failure, seizure, bacterial infection, hemorrhage, hypotension, vomiting, tachycardia, pyrexia, volume depletion, fracture, dyspnea, transaminases elevation, diarrhea, fungal infection, anemia, and local administration reaction.

“This milestone represents the culmination of decades of research into better understanding and ultimately finding an effective treatment for Menkes disease,” said Dr. Stephen Kaler, a clinical genetics and genomics specialist at the Columbia University Medical Center. “Increased awareness of Menkes disease and rapid testing upon suspicion are critical, as beginning copper histidinate therapy in affected neonates has been shown to reduce symptoms and prolong life.”

Acquired from Cyprium Therapeutics in 2023, Sentynl has advanced Zycubo through the final stages of development with the FDA based on positive results from pivotal studies, receiving Breakthrough Therapy, Fast Track, Rare Pediatric Disease, and the FDA Orphan Drug Designations. Copper histidinate has also been granted Orphan Designation by the European Medicines Agency.

Tenpoint Therapeutics, Ltd., a global, commercial biotechnology company focused on developing groundbreaking treatments to improve vision in the aging eye, today announced that the U.S. Food and Drug Administration (FDA) approved Yuvezzi (carbachol and brimonidine tartrate ophthalmic solution) 2.75%/0.1%, previously known as Brimochol™ PF, the first and only dual-agent eye drop for the treatment of presbyopia in adults. Presbyopia, the gradual loss of near vision that typically begins around age 45, affects about two billion people globally and 128 million people in the U.S.3,4,5 Yuvezzi is expected to be broadly commercially available in the U.S. in Q2 2026.

Carbachol

brimonidine 

Yuvezzi (carbachol and brimonidine tartrate ophthalmic solution) 2.75%/0.1% isthe only dual-agent presbyopia-correcting eye drop intentionally designed to deliver durability, tolerability, and safety

Yuvezzi was studied in two pivotal Phase 3 trials enrolling more than 800 patients, including the world’s largest and longest safety study for presbyopia eye drops1,2

Yuvezzi achieves miosis from 30-minutes up to 10 hours with one drop daily1

The FDA approval of Yuvezzi is based on positive data from two Phase 3 studies. The Phase 3 BRIO I study demonstrated a superior benefit of the combination therapy over the individual actives – a requirement for FDA approval of a fixed-dose combination.1 In the second Phase 3 study, BRIO II, which was vehicle-controlled, Yuvezzi achieved all primary near vision improvement endpoints with statistically significant three-lines or greater improvement in binocular uncorrected near visual acuity (BUNVA) over 8 hours, without the loss of one line or more in binocular uncorrected distance visual acuity (BUDVA).2 In addition, Yuvezzi was well-tolerated with no treatment-related serious adverse events observed in the more than 72,000 treatment days monitored in BRIO II, the longest safety study (12 months) conducted in presbyopia to-date.2 The most common side effects of Yuvezzi are headache, impaired vision and temporary eye pain or eye irritation.6

Eye redness was not a commonly reported side effect in clinical trials of Yuvezzi. In BRIO I and BRIO II the reports of adverse events of ocular hyperemia (eye redness) were low.1,2 In BRIO II, the rate of reported adverse events of ocular hyperemia (eye redness) was lower in subjects receiving Yuvezzi (2.8%) than carbochol alone (10.7%).2

“The FDA approval of Yuvezzi represents a significant milestone for the millions of people in the U.S. living with presbyopia and its daily frustrations and challenges,” said Henric Bjarke, Chief Executive Officer of Tenpoint Therapeutics. “As the first FDA-approved dual-agent eye drop for presbyopia, Yuvezzi leverages the mechanisms of carbachol and brimonidine tartrate to deliver sharp near vision with favorable tolerability. People deserve treatments that not only work but also can fit conveniently into their daily lives, and Yuvezzi brings an innovative new option to the presbyopia category. This approval marks the first groundbreaking therapy for Tenpoint Therapeutics aimed at advancing our mission to bring innovation to the aging eye.”

“The impact of presbyopia is often underestimated, and current solutions like glasses, contacts or surgery have fallen short in meeting the real-world needs of people who struggle with close-up tasks,” said John Hovanesian, M.D., FACS, of Harvard Eye Associates in Laguna Hills, California. “Yuvezzi introduces a novel approach by combining carbachol and brimonidine tartrate in a single daily eye drop that sharpens near vision and maintains tolerability throughout the day. Yuvezzi was intentionally designed to deliver both efficacy and tolerability, which represents an important step forward in delivering a complete, noninvasive option for people with presbyopia.”

“Presbyopia remains a universal and progressive condition that requires individualized management strategies,” said Mile Brujic, OD, FAAO, of Premier Vision Group in Bowling Green, Ohio. “I’m excited that I will be able to offer my patients YuvezziTM, the first-of-its-kind eye drop well-suited for long-term use. For people seeking a reliable, lifestyle-friendly solution to manage their near vision challenges in aging eyes, Yuvezzi is a valuable and practical advancement.”

“We’ve been working diligently to bring Yuvezzi to the eye care community and to the millions of adults looking for the optimal solution to address their frustration with presbyopia,” said Carol Kearney, Chief Commercial Officer of Tenpoint Therapeutics. “It was important to us that we provide an option that fits seamlessly into active, social and professional lifestyles, and we intentionally designed Yuvezzi to offer the right balance of efficacy, tolerability and ease of use.”

FDA Approves Bysanti (milsaperidone) for the treatment of Bipolar I Disorder and Schizophrenia

Vanda Pharmaceuticals Inc. (Nasdaq: VNDA) today announced that the U.S. Food and Drug Administration (FDA) has approved Bysanti (milsaperidone) tablets, a first line therapy for the acute treatment of manic or mixed episodes associated with bipolar I disorder and for the treatment of schizophrenia in adults.

Bysanti is a new chemical entity (NCE) that belongs in the class of atypical antipsychotics. In clinical studies Bysanti demonstrated bioequivalence to iloperidone across the therapeutic dosing spectrum enabling it to leverage well-established knowledge of efficacy and safety derived from a rich clinical development program and more than 100,000 patient-years of real-world experience with Fanapt® (iloperidone). As such Bysanti represents a novel therapeutic option with a trusted safety profile in the treatment of these serious psychiatric conditions.

"The Bysanti approval marks a significant step forward, offering patients and providers a reliable new treatment grounded in extensive clinical heritage," said Mihael H. Polymeropoulos, M.D., President, CEO and Chairman of the Board of Vanda Pharmaceuticals. "Bysanti exemplifies a new era of accelerated innovation in drug development that can transform how we address unmet needs in behavioral health."

Bysanti is currently being tested as a once-daily adjunctive treatment in treatment-resistant major depressive disorder in an ongoing clinical study expected to complete by the end of this year.

Bysanti (milsaperidone), a new chemical entity, rapidly interconverts to iloperidone, providing dual active molecules that work in tandem by antagonizing dopamine D2, serotonin 5-HT2A, and alpha1-adrenergic receptors to modulate key pathways in these disorders. Its safety profile aligns closely with that established for iloperidone.

Bysanti's unique in-class receptor binding profile, featuring strong alpha-adrenergic binding in excess of dopamine and serotonin receptor binding, makes it suitable for further investigation in conditions that include symptoms of hostility, agitation, and hyperarousal.

Caffeine reversed memory problems caused by sleep deprivation

In continuation of my update on Caffeine

Researchers at the Yong Loo Lin School of Medicine at the National University of Singapore (NUS Medicine) have found that caffeine can help restore a specific type of memory that is impaired by sleep deprivation. The findings, published in Neuropsychopharmacology, reveal how caffeine acts on a well-defined brain pathway involved in social memory, the ability to recognize and distinguish people we have encountered before.

The research provides new insight into how sleep loss affects the brain and suggests that caffeine's benefits may extend beyond simply increasing alertness.

How Sleep Loss Affects Social Memory

The study was led by Associate Professor Sreedharan Sajikumar and first author Dr. Lik-Wei Wong from the Department of Physiology and the Healthy Longevity Translational Research Program at NUS Medicine.

The team focused on a part of the brain known as the hippocampal CA2 region. The hippocampus is critical for learning and memory, while the CA2 area plays a particularly important role in forming social memories. This brain region also receives signals involved in regulating sleep and wakefulness.

To investigate the effects of sleep deprivation, the researchers subjected laboratory animals to five hours of sleep loss. Afterward, caffeine was provided in drinking water for unrestricted consumption over a seven-day period.

Caffeine Restored Brain Communication

Caffeine is a stimulant that blocks adenosine receptor signaling pathways. Adenosine accumulates during periods of wakefulness and helps reduce brain activity, contributing to feelings of sleepiness.

The researchers then performed electrophysiological recordings on hippocampal tissue samples to assess synaptic plasticity, the brain's ability to strengthen or weaken connections between nerve cells in response to experience and learning.

The results showed that sleep deprivation disrupted the maintenance of synaptic plasticity in the CA2 region. Communication between neurons weakened, reducing the brain's capacity to strengthen important neural connections. These changes were accompanied by noticeable deficits in social recognition memory.

Overall, the findings demonstrated that sleep loss impaired both brain function and behavior through a specific neural circuit.

A Targeted Effect on Memory Circuits

The researchers also found that caffeine administered before sleep deprivation restored synaptic communication in the CA2 region and returned plasticity to normal levels.

As a result, the social memory deficits caused by sleep loss were reversed. Importantly, caffeine's effects were highly selective. Rather than broadly increasing activity throughout the brain, it specifically restored the disrupted pathway linked to social memory.

This targeted action meant that animals in the control group that had not experienced sleep deprivation did not show signs of excessive neural stimulation despite receiving caffeine.

"Sleep deprivation does not just make you tired. It selectively disrupts important memory circuits," noted Dr. Wong. "We found that caffeine can reverse these disruptions at both the molecular and behavioral levels. Its ability to do so suggests that caffeine's benefits may extend beyond simply helping us stay awake."

Assoc Prof Sajikumar added, "Our findings position the CA2 region as a critical hub linking sleep and social memory. This research enhances our understanding towards the biological mechanisms underlying sleep-related cognitive decline. This could inform future approaches to preserving cognitive performance."

Implications for Brain Health and Future Research

The findings highlight the essential role sleep plays in maintaining healthy cognition and memory. By showing that caffeine can restore specific neural pathways affected by sleep deprivation, the study provides new insight into potential targeted approaches for addressing cognitive decline.

The researchers plan to continue investigating how caffeine influences memory consolidation and memory retrieval. Future studies will also use targeted manipulations of brain circuits to better understand the causal relationship between neural pathways and memory function.
